- 3-Phase 3-Wire
- 4:1 ratio 12.5 VA
The VersaPack™ is part of the FlexPack
System™ PVDT transformers from TSTM. The associated models (ratio’s)
are the same revenue-accuracy toroidal autotransformer in the VT Packs™.
The transformer is individually encased in epoxy inside a flame
retardant polycarbonate enclosure.
The VersaPack “System” is for use with modern wide voltage range solid state meters as well as older induction (disk-type) watthour meters where traditional VT’s are used. The VersaPack 4:1 ratio transformer is used in single phase, three phase 3-wire delta or three phase 4-wire delta applications based upon a 120V secondary. The number of transformers required are:
Single phase 2 or 3-wire, 480V is (1) or (2) based upon the meter Form 3S or 4S
Three phase 3-wire delta, 480V is (2) for meter Form 5S, 35S/45S
The VersaPack™ mounts on a required TSTM Backplane very much like a single-phase residential circuit breaker. The Backplane, which can accept up to three VersaPacks™, can be mounted in a pad mount transformer, transformer cabinet, in one of our enclosures designed for that purpose ( refer to “Product” page, “Enclosure” tab, Long Narrow or Universal ), or other convenient location. . Many meter socket manufacturers offer “extended” sealed compartments to accommodate the VersaPack / Backplane isolating the 480 volts. The VersaPack™ is not designed to be mounted outdoors.
